2 Claims.

This invention relates `to advertising sign display boxes adapted to besupported on parking meter standards.

Heretofore some attention has been given to boxes of this type, but sofar as I know no adequate means has been provided for easy assembly,installation andr removal of the boxes from parking meter standards..The insertion and removal of .the advertising cards, also, has created aproblem.

In view of thoforegoing, one of the objects of my invention is toprovide a sign display box for parking meter standards which can beinstalled on the. standard supporting the parking meter, and removedtherefrom with the parking meter in place at the top of the standard andwithout disturbing it Another object is to provide a sign display boxwhich may be easily and cheaply madev of metal or other durablematerials, and may be easily and quickly assembledinr place. on verticalparking meter standards;

.Another object is to provide a display box, as above stated, which ismechanically sturdy and weather prooi and having weather proof windowssecured. inplace by key screws;

Another object is tok provide a box of ythis type which, when fullyassembled., cannotbe removed without the use of a-proper key-pand havingsign viewing panels adaptedto reasy sliding removal. and replacement,and with means in the. body of said caseicr locking saidpanels in placeby means of a key screw, operated by a specially formed key.

Other objects will appear hereinafter.

I attain the foregoing objects by means of the devices and theconstruction illustrated in the accompanying drawings, in which- Figure1 is, a front elevational View of a sign display box embodying myimprovements and attached to a meter box standard below the meter box;

' Figure 2, ain-elevational view ofthe back half of the box with thefront removed.

Figure 3 is a perspective view of one part of the box case showing theinterior thereof and drawn on an enlarged scale;

Figure 4, a side elevational view of the box with a portion of the wallcut away to show interior construction; and

Figure 5 is a fragmentary section of a portion of one side of the casebottom showing details of the display panel lock screw and a key for usetherein.

Similar numerals refer to similar parts in the several views:

The box'body 2` is composed of two similarly formed complementary halves3f and 4 which are preferablycast from light metal and are Yduplicatesofeach other. Body 2 nts on standard 5 below meter box 6 and is adaptedYto display sign 'l on .panels l2.

Each body half is substantially rectangular in' shape andhas aperimetralfenclosure or rim including a top end plate 8, a bottom endplate 9 andside plates I0. The outer portitml has an opening il and .isadapted to be closed by sign display panel I2.

The plates boundingopening Ilfhave inwardly extending iianges i3 alongtheir outer edges forming a frame toenclose panel-I2.

Grooves lll are formed in the inner faces of these anges and aredimensioned to receive the edges of panel l2 with an easy sliding lit.Along the outer edge oi` top end plate 8 a somewhat deeper ange i6 isformed..v This is also provided with a groove. I5 which is in thesamefplane as thatv of the sidegrcoves. The bottom end flange I9 isprovided with a slot il. It` is to be noted that this structure enablesa display panel I2 to loe-inserted through slot il and slide up intoopening H where it is. retained in the frame composed of thev top` and`side slots.

. The inner edge 2@ of the rim of each parta/buts the. correspondingedge of vthe other complementary casepart. In the central portion of theend plate. 8 of each .case parta semi-circular notch 22 is. formed.VThis notch .mates with a correspending notch .in the complementary casepart and bothare shaped, toy fit closely-around stand-Y ard 5.

Afsimilar semi-circularA notch V2d is formed in the inner .edge otthebottom end plate 9 of each case part. These .notches mate in aposition ver tically alined with the notchesV 22 in the top end platesofthe two case .parts and` likewise fit around standard 5..

Itis nowto. be noted thaty top end plate 8 is not flat but has a raisediiat central portion and angularly downwardly and outwardly slantingside portions. This plate is shaped in this manner to shed rain and thelike, and, obviously, may be made arcuate, if desired.

The two complementary case parts are held together by securing screws 25extending through securing lugs 26 on one of said case parts andthreaded into similarly positioned lugs in the opposite case part. Theselugs are supported within the case parts by webs 28 whereby theircenters are within the boundary of inwardly extending flanges I3, sothat screws 25 can easily be reached by a screw driver when panels I2are removed from openings II.

A positioning lug 21 is formed on the inner face of top end plate 8adjacent the center of notch 22. This lug is drilled in alinement withthe radius of the semi-circular notch and tapped to receive a set screwI8.

On bottom end plate 9 and adjacent the bottom of the notch therein is asimilar lug 36. This lug is similarly drilled, tapped and provided witha set screw at 32. Directly below and aligned therewith is a tapped hole34 which is adapted to receive a hollow headed locking screw 35.

The bottom flange I9 is provided with a broached key hole 31 which isalined with hole 34. The key 38 Which is adapted to t into the head ofscrew 36 may have :a hexagonal section. or any other non-circularsection. The head of this screw has a hole adapted to receive this key.Likewise, key hole 3l' is broaohed to have a hexagonal or othernon-circular shape to just receive the end 40 of the key. The shank 39of the key however is rounded and of reduced size so that it will turnfreely in the key hole after it is inserted into the key hole andinserted in the hole in the head of screw 3S.

When the display panels I2 are to be inserted through slots I1 thelocking screws 3S are threaded into lugs 30 until their heads are flushwith the inner face of slots I7. No obstruction is, therefore, offeredto the insertion of the panels I2. However, when they are to be lockedin place the keys 38 are screwed outward until they extend :across slotsII and therefore provide a complete obstruction to the withdrawal of thepanels.

Panels I2 preferably are made of three layers. The outer layers 45 and46 are made of transparent plastic material and the center layer 41 isof paper, card board, or other suitable material on which the displaynotice or advertising 48 is marked.

From the foregoing it will be readily understood that the two casehalves 3 and 4 may easily be applied to the standard 5, withoutdisturbing the meter box 6. To fasten the parts together around thestandard it is only necessary to drive the four securing screws 25. Thevertical position of the box body 2, thus formed may then be fixed bydriving set screws I8 and 30. Thereafter the panels I2 are slid upwardinto position, closing openings I I, and locked .in place by screwinglocking screws 36 out into slots I'I, in each of the case halves. Thepanels may be easily removed by a reverse procedure. Unauthorizedremoval of the panels is extremely diiicult without a properly tted key.Unless the key has a cross section shaped to fit into the broached keyholes it cannot be inserted. Unless its end is properly fitted it willnot enter the heads of the locking screws; and, unless the key shank hasa 4 rounded and reduced section it cannot turn in the keyhole.

Having now fully described my invention and explained its use I wish tobe limited only by the claims.

I claim:

In a sign display box for installation on a parking meter standardcomposed of two mating complementary halves adapted to iit together toforma box body enclosing a parking meter standard, a box body half,including, a rim having side plates and top and bottom end plates havingmating inner edges inwardly extending flanges having grooves on theirinner edges formed on the outer edges of said top and side plates ofsaid rim providing a display panel frame, a slot alined with saidgrooves formed in the bottom plate of said rim adapted to admit a signdisplay panel to slide upward into said top and side grooves, securinglugs adapted to receive securing screws positioned within said rim anddisposed adjacent the side plates thereof; notches adapted to receive aparking meter standard formed in vertically alined positions on theinner edges of said top and bottom plates, positioning lugs within saidcase halves formed on the inner faces of said top and bottom platesadjacent the bottoms of said notches having set screws adapted to bearon a standard positioned in said notches, a panel locking screw threadedinto said positioning lug on said bottom plate and adapted to screwoutward therefrom across the slot in said bottom plate and a key holebroached to receive a key having a non-circular section formed in theouter portion of said lower plate and alined with said locking screw.
